DETAILED DESCRIPTION OF SPECIFIC EMBODIMENTS

Specific embodiments of the present disclosure will be described herein.In an effort to provide a concise description of these embodiments, allfeatures of an actual implementation may not be described in thespecification. It should be appreciated that in the development of anysuch actual implementation, as in any engineering or design project,numerous implementation-specific decisions must be made to achieve thedevelopers' specific goals, such as compliance with system-related andbusiness-related constraints, which may vary from one implementation toanother. Moreover, it should be appreciated that such a developmenteffort might be complex and time-consuming, but would nevertheless be aroutine undertaking of design, fabrication, and manufacture for those ofordinary skill having the benefit of this disclosure.

The subject matter disclosed herein relates to surface-mountedwedge-style anti-ram security barriers. More specifically, embodimentsof the present disclosure include wedge-style barriers that may besecured to a shallow foundation or surface and/or may be flush at grade.In other words, the wedge-style barriers disclosed herein are capable ofoperation without being mounted in below grade pits. Traditionalwedge-style barriers, and components to lift such barriers, aregenerally housed in below grade pits, which can complicate maintenanceand repair of the wedge-style barriers. For example, drainage and debrisremoval beneath the wedge-style barriers, which are important forwedge-style barriers to operate properly, can be difficult.Additionally, repair or removal of traditional wedge-style barriersrequires the complete installation to be removed and replaced.

As discussed in detail below, the surface-mounted configuration ofpresent embodiments enables a reduction in drainage and debris removalefforts below the wedge-style barriers. Furthermore, as the wedge-stylebarrier is capable of being mounted above grade, various components ofthe wedge-style barrier may not be exposed to harsh environments belowgrade, where debris and other material may collect. Moreover, componentsof the disclosed wedge-style barriers may be bolted together, whichenables easier and improved maintenance, repair, or replacement of anindividual component. For example, in the event of a nuisance orintentional impact with the wedge-style barrier, the damaged componentscan be replaced in short order. As discussed in detail below, when thesurface-mounted wedge-style barrier is in a retracted position, thewedge-style barrier may serve as a traffic calming system, such speedtable or bump. However, in other embodiments, the wedge-style barriermay be flush with a surrounding surface when in the retracted position.When the surface-mounted wedge-style barrier is in a deployed position,the wedge-style barrier may function as an anti-ram security barrier toreduce or block access to a property or path.

In the following discussion, reference is made to a surface of afoundation to which the wedge-style barrier is mounted. As discussedbelow, the wedge-style barrier is coupled to an upper side of an anchoror subframe secured within a foundation. For example, in the illustratedembodiments, the upper side of the anchor is substantially flush withthe surface of the foundation. In such embodiments, the wedge-stylebarrier may be mounted directly to the surface of the foundation.However, in other embodiments, the upper side of the anchor may beslightly raised above the surface of the foundation or slightly recessedbelow the surface of the foundation.

FIG. 1 is a front perspective view of an embodiment of a surface-mountedwedge-style barrier 10. As shown, the barrier 10 is mounted to a surface12 of a foundation 14 (e.g., a shallow foundation). For example, thefoundation 14 and the surface 12 to which the barrier 10 is secured maybe made from concrete. As discussed below with reference to FIG. 2, thebarrier 10 is mounted to or includes an anchor or subframe (e.g., anchor30 shown in FIG. 2) secured beneath the surface 12. For example, thebarrier 10 may be bolted to the anchor or secured to the anchor by othermechanical fasteners.

In the illustrated embodiment, the barrier 10 includes a wedge plate 16,which includes a portion that is substantially parallel with the surface12 when the barrier 10 is in the retracted position. As a result, thebarrier 10 may serve as a traffic calming system, such as a speed tableor speed bump. In other words, vehicles or people may pass over thebarrier 10 when the barrier 10 is in the retracted position andexperience slight elevation relative to the surface 12 while on thebarrier 10. As discussed in detail below, when the barrier 10 is in thedeployed position, the wedge plate 16 is held and supported in a raisedposition by a lifting mechanism of the barrier 10. When the barrier 10is in the deployed position, the wedge plate 16 may block vehicles orpeople from passing over or through the barrier 10. In certainembodiments, the wedge plate 16 may be made from a metal, such as steel.

The barrier 10 includes a variety of components, indicated in FIG. 1 byreference numeral 18, disposed beneath the wedge plate 16. As discussedin detail below, the components 18 serve to lift and support the wedgeplate 16 when the barrier 10 is in the deployed position. In certainembodiments, the components 18 may be off-the-shelf parts or othercomponents that are readily available. Additionally, the components 18may be bolted or otherwise mechanically coupled to one another. In thismanner, repair or replacement of one or more components 18 may besimplified and streamlined. That is, repair or replacement of singlecomponents 18 may be done more quickly, easily, and cost effectively.

FIG. 2 is a side view of the surface-mounted wedge-style barrier 10 in aretracted position, illustrating the securement of the barrier 10 to ananchor 30 secured beneath the surface 12 of the foundation 14. Incertain embodiments, the anchor 30 may be a steel frame includingplates, beams (e.g., I-beams), and/or other structures that are securedwithin the foundation 14, which may be concrete. At the surface 12, anupper side 28 of the anchor 30 may be at least partially exposed,thereby enabling the attachment of the barrier 10 to the anchor 30. Forexample, holes or apertures 31 (e.g., threaded holes) in one or morebeams or plates of the anchor 30 may be exposed to the surface 12. Inthis manner, bolts 32 or other mechanical fasteners may be used tosecure the barrier 10 to the anchor 30. As the barrier 10 is mounted tothe surface 12 of the foundation 14, collection of debris and othermaterial beneath the barrier may be reduced, and components of thebarrier 10 may not be exposed to below grade environments.

As mentioned above, in the retracted position, the wedge plate 16 of thebarrier 10 is lowered and its main or upper portion 33 is substantiallyparallel with the surface 12. As a result, vehicles and/or people maypass over the barrier 10. Additionally, the barrier 10 may serve as atraffic controlling device when in the retracted position. In theillustrated embodiment, the wedge plate 16 acts as a speed table in theretracted position. That is, when the barrier 10 is in the retractedposition, the upper portion 33 of the wedge plate 16 is elevated adistance 34 above the surface 12 that facilitates passage of vehiclesover the barrier. As shown, the wedge plate 16 includes an inclineportion 36 which enables a person or vehicle traveling along the surface12 and toward the barrier 10 to transition up the distance 34 and thenacross the upper portion 22 of the wedge plate 16. In certainembodiments, the distance 34 may be approximately 5, 6, 7, 8, 9, 10, or12 inches. Furthermore, the upper portion 22 of the wedge plate 16 issubstantially flush with an elevated surface 38 of the foundation 14 ata rear 40 of the barrier 10. As a result, a traveling vehicle or personmay pass across the wedge plate 16 of the barrier 10 and onto theelevated surface 38 of the foundation 14. The foundation 14 furtherincludes a decline portion 42, which decreases the grade of thefoundation 14 by the distance 34 to be level with the surface 12.Consequently, the barrier 10 and the elevated surface 38 of thefoundation 14 may jointly serve as a traffic calming system (e.g., aspeed table or speed bump).

FIG. 3 is a schematic top view of the surface-mounted wedge-stylebarrier 10 in a retracted position, illustrating a lifting mechanism 50of the barrier 10. As mentioned above, the lifting mechanism 50 isconfigured to lift and support the wedge plate 16 when the barrier 10 isin the deployed position. As indicated by reference numeral 52, thelifting mechanism 50 includes components disposed beneath the wedgeplate 16. For example, the components 52 beneath the wedge plate 16 mayinclude an electromechanical actuator, a cam, one or more cam surfaces,and so forth.

Additionally, the lifting mechanism 50 includes a spring assembly 54.The spring assembly 54 is disposed within a recess 56 formed in theelevated surface 38 of the foundation 14 and includes a spring rod 58with one or more springs 60 disposed about the spring rod 58. The springrod 58 is coupled to a cam (e.g., cam 80 shown in FIG. 4) of the liftingmechanism 50. The springs 60 disposed about the spring rod 58 are heldin compression by spring supports 62, including a fixed spring support64. That is, the fixed spring support 64 is fixed relative to thefoundation 14 and the rest of the barrier 10. Additionally, the springsupport 62 at the end of the spring rod 58 (e.g., spring support 65) maybe fixed to the end of the spring rod 58 to enable compression of thesprings 60. As the springs 60 are compressed between the spring supports62, the spring assembly 54 generates a force acting on the cam coupledto the spring rod 58 in a direction 66. The force created by the springassembly 54 reduces the remaining force needed to move the cam and liftor deploy the wedge plate 16. For example, the remaining force appliedto the cam to deploy the wedge plate 16 may be provided by anelectromechanical actuator 84 or other actuator. As such, the springassembly 54 and the actuator 84 (e.g., electromechanical actuator) mayoperate together to translate the cam and lift the wedge plate 16. Asdiscussed in detail below, when the cam is translated in the direction66, the cam translates along and between curved or arcuate cam surfaces,thereby spreading the cam surfaces apart and lifting the wedge plate 16.

As mentioned above, the spring assembly 54 exerts a constant force onthe cam, while the electromechanical actuator may be controlled to exerta variable force on the cam, thereby enabling the lifting and lowering(i.e., deploying and retracting) of the wedge plate 16. In certainembodiments, the constant force applied by the spring assembly 54 may beadjustable. For example, the tension or force generated by the springs60 may be adjusted such that the barrier 10 may fail up, mid-way, ordown if the actuator (e.g., electromechanical actuator) is disabled.

As will be appreciated, the spring assembly 54 may be covered andprotected from debris or other elements by a cover plate (e.g., coverplate 68 shown in FIG. 4) that may be substantially flush with theelevated surface 38 of the foundation 14. Furthermore, the springs 60are located on a protected side (e.g., a back or rear side) of thewedge-style barrier 10. In this manner, the springs 60 may be easilyaccessible for maintenance, while also protecting the springs 60 fromtampering or disablement. The lifting mechanism 50 is described infurther detail below, with reference to FIG. 6.

FIG. 4 is a front perspective view of an embodiment of thesurface-mounted wedge-style barrier 10, illustrating the barrier 10 in adeployed position. That is, the wedge plate 16 is lifted and supportedby the lifting mechanism 50. As mentioned above, in the deployedposition, the wedge plate 16 serves to block access or travel beyond thebarrier 10. For example, the barrier 10 (e.g., the wedge plate 16) mayblock pedestrians or vehicles from accessing a property or pathway.

As discussed above, the barrier 10 is attached to the anchor 30 securedwithin the foundation 14, thereby mounting the barrier 10 to thefoundation 14. As shown in the illustrated embodiment, the barrier 10 issecured to the surface 12 (e.g., the anchor 30) with brackets 70 (e.g.,L-shaped brackets). For example, the brackets 70 may be coupled to theanchor 30 beneath the surface 12 by bolts, nuts, threaded fasteners, orother types of mechanical fasteners. In the illustrated embodiment, thebarrier 10 includes front brackets 71 and rear brackets 73. The rearbrackets 73 are fixed to the surface 12 (e.g., the anchor 30) and arecoupled to the wedge plate 16 to form a hinged connection. The hingedconnection between the wedge plate 16 and the rear brackets 73 enablethe wedge plate 16 to pivot about the rear brackets 73.

The front brackets 71 are coupled to respective linkage assemblies 72that are further coupled to an underside 74 of the wedge plate 16 withadditional front brackets 71. For example, barrier 10 may include 2, 3,4, 5, 6, or more linkage assemblies 72 disposed between the surface 12and the wedge plate 12 and coupled to respective front brackets 71. Thelinkage assemblies 72 may each include one or more bars or other membersthat are coupled to the front brackets 71. The bars or other members ofthe linkage assemblies 72 may be coupled to one another by bolts, pins,or other coupling mechanisms that enable the bars of the linkageassemblies 72 to pivot relative to one another. The bars or members ofthe linkage assemblies 72 may be similarly coupled to the front brackets71 fixed to the surface 12 and the wedge plate 16. As a result, thelinkage assemblies 72 may pivot and rotate to enable the collapse andextension of the linkage assemblies 72 during retraction and deploymentof the barrier 10.

The linkage assemblies 72 cause movement of the wedge plate 16 to berestricted. For example, if a vehicle is traveling towards the deployedwedge plate 16 (e.g., in a direction 78), the linkage assemblies 72 andthe front brackets 71 may restrict movement of the wedge plate 16 (e.g.,upward movement) beyond a certain point. In other words, the wedge plate16 may remain relatively fixed in the deployed position, therebyenabling the wedge plate 16 to block a vehicle traveling towards thebarrier 10. Indeed, the barrier 10 may be configured to stop a vehicletraveling at approximately 30, 40, 50 miles per hour or more.

As shown, the lifting mechanism 50 includes a cam 80 disposed betweencam surfaces 82 (e.g., curved or arcuate cam surfaces). The liftingmechanism 50 further includes an electromechanical actuator 84 coupledto the cam 80. The operation of the electromechanical actuator 84, thecam 80, and the cam surfaces 82 is discussed in further detail withrespect to FIG. 5. In the illustrated embodiment, the barrier 10 alsoincludes safety legs 86 coupled to the underside 74 of the wedge plate16 by additional brackets 70. The safety legs 86 may be deployed orextended to support the wedge plate 16 when the wedge plate 16 is in thedeployed position. For example, in one circumstance, the safety legs 86may be extended during maintenance of the barrier 10. When the safetylegs 86 are deployed, the safety legs 86 support the weight of the wedgeplate 16 against the surface 12. As a result, the lifting mechanism 50may be deactivated, serviced, removed, replaced, and so forth.Additionally, other components of the barrier 10 may be replaced whenthe safety legs 86 are extended and supporting the wedge plate 16 in thedeployed position.

FIG. 5 is partial perspective view of an embodiment of thesurface-mounted wedge-style barrier 10, illustrating the cam 80 and thecam surfaces 82 of the lifting mechanism 50. Specifically, two camsurfaces 82, which are referred to as lower cam surfaces 83, arepositioned below the cam 80. The lower cam surfaces 83 may be fixed tothe surface 12 (e.g., anchor 30) by a mounting plate 85. For example,the lower cam surfaces 83 and the mounting plate 85 may form a singlepiece that is secured to the anchor 30 by bolts or other mechanicalfasteners. Additionally, two cam surfaces 82, which are referred to asupper cam surfaces 87, are positioned above the cam 80 and coupled to(e.g., welded) to the underside 74 of the wedge plate 16. In otherembodiments, intervening layers or plates may be positioned between thesurface 12 and the lower cam surfaces 83 and/or the wedge plate 16 andthe upper cam surfaces 87

As mentioned above, the cam 80 translates along the cam surfaces 82 whenthe wedge plate 16 is lifted from the retracted position to the deployedposition. Specifically, the electromechanical actuator 84, which iscoupled to the cam 80 by a rod 100 in the illustrated embodiment,applies a force in a direction 102, which moves the cam 80 in thedirection 102. Additionally, as mentioned above, the spring assembly 54(see FIG. 3) may provide a force acting on the cam 80 in the direction102 via spring rod 58, which may reduce the force the electromechanicalactuator 84 is required to apply to the cam 80 in order to actuate andlift the wedge plate 16. As the cam 80 travels along the cam surfaces82, which are curved, in the direction 102, the wedge plate 16 is liftedfrom the retracted position (see FIG. 1) to the deployed position (seeFIG. 4). As shown, the cam 80 includes track wheels 104 (e.g., rollers),which contact and translate along the cam surfaces 82 during operation.That is, the track wheels 104 rotate about a bar 106 as the track wheels104 translate along the cam surfaces 82. In certain embodiments,bushings may be disposed between the track wheels 104 and the bar 106 tofacilitate or improve rotation of the track wheels 104. For example, thebushings may be made from a metal, such as brass.

FIG. 6 is a schematic top view of the lifting mechanism 50. As discussedabove, the lifting mechanism 50 includes the spring assembly 54 and theelectromechanical actuator 84 coupled to the cam 80. Springs 60 aredisposed about the spring rod 58 and are held in compression by springsupports 62, including the fixed spring support 64, which is fixedrelative to the foundation 14 and the barrier 10, and the spring support65, which is fixed to the end of the spring rod 58. The spring assembly54 is coupled to the cam 80 by extension brackets 120. Specifically, theextension brackets 120 couple the spring rod 58 to the bar 106 of thecam 80. As a result, the force generated by the spring assembly 54 actson the cam 80 in the direction 66.

Additionally, as discussed above, the electromechanical actuator 84 iscoupled to the cam 80 by a rod 100. During deployment of the barrier 10,the electromechanical actuator 84 applies a force on the cam 80 in thedirection 66, which causes the cam 80 to move in the direction 66. Asdiscussed above, when the cam 80 is actuated in the direction 66, thetrack wheels 104 of the cam 80 translate along the cam surfaces 82 ofthe barrier 10, thereby lifting the wedge plate 16 from a lowered (e.g.,retracted) position to a raised (e.g., deployed) position.

FIG. 7 is a front perspective view of an embodiment of thesurface-mounted wedge-style barrier 10, illustrating the barrier 10 in aflush-mounted configuration. That is, when the barrier 10 is in theretracted position, the wedge plate 16 will be substantially flush withthe surface 12. Accordingly, the barrier 10 is mounted within a recess130 formed in the foundation 14.

The barrier 10 shown in FIG. 7 includes similar elements and elementnumbers as the embodiments discussed above. For example, as similarlydescribed above with respect to FIG. 2, the barrier 10 may be secured tothe anchor 30 disposed beneath a bottom surface 132 of the recess 130.As the wedge plate 16 is substantially flush with the surface 12 of thefoundation 14 when the barrier 10 is in the retracted position, thebarrier 10 may not serve as a traffic calming device when the barrier 10is in the retracted position. Rather, the barrier 10 may not interruptfoot or vehicle traffic at all when the barrier 10 is in the retractedposition.

As discussed in detail above, the present disclosure is directed towardssurface-mounted wedge-style anti-ram security barriers. Specifically,embodiments of the present disclosure include wedge-style barriers thatmay be secured to a shallow foundation or surface and/or may be flush atgrade. For example, a wedge-style barrier in accordance with presentembodiments may operate without being mounted in a below grade pit. Thesurface-mounted configuration enables a reduction in drainage and debrisremoval efforts below the wedge-style barriers. Furthermore, as thewedge-style barrier may be mounted above grade, various components ofthe wedge-style barrier may not be exposed to harsh environments belowgrade, where debris and other material may collect. Moreover, variouscomponents of the disclosed wedge-style barriers may be bolted together,which enables easier and improved maintenance, repair, or replacement ofan individual component. As discussed above, when the surface-mountedwedge-style barrier is in a retracted position, the wedge-style barriermay serve as a traffic calming system, such speed table or bump.However, in other embodiments, the wedge-style barrier may be flush witha surrounding surface when in the retracted position. When thesurface-mounted wedge-style barrier is in a deployed position, thewedge-style barrier may function as an anti-ram security barrier toreduce or block access to a property or path.
